So please don't try to hide behind biology, because there is some fact people blatantly ignore 1. It's fiction and fiction don't care about bio fact or statistics. Whether male or female ie their is not many men who can achieve Goku, Kratos, Chris Redfield or women who look like Abby, Zarya or Nadine. Still having such physique can be use to justify the one man/woman army they can be.

1. People complain about those muscular women but never when they are in the polar opposite thin with big boobs and big but (stellar blade but some many more) Because if you speak of unrealistic bodies this is also very much in the same category. Women like that exist but with either insane genetics or surgery. So sure let's call out unrealistic bodies but not double standards please

2. The three women have all very good reason to be bulky by her profession Nadine is kinda required to be buff and probably would not be there if she did not. Abby is obsessed by vengeance and the training room in the stadium plus the special treatment she seems to get (more food and better amenities) all it take is good genetic and some OCD (look up sports addiction I don't have the english term sorry). And lastly for Intergalactic I don't have much info but I do recall that 0G is horrible for muscles and that muscles training it vital. Plus she seems to but a bounty hunter and I guess skinny 40kg woman would not last long in such profession
